This guide contains information about excavator track motor, working, the lifetime of an excavator track motor, applications, benefits, cost of an excavator track motor, leakage in excavator track motor, and much more.

The practical information in this FAQ guide will prove fruitful for you, no matter if you are familiar with this component or unfamiliar.

1.    How does an excavator track motor work?

The working process of an excavator track motor is described below:

An excavator hydraulic pump is a mechanism that supplies the fluid to operate the track motor.

A tracking motor is the part of the machine that moves the track to change the direction of the motion.

It acts as a powering source for the final drive, transforming that energy into useful mechanical power.

The rotational motion is delivered from the flywheel to the sprocket.

Once the wheel turns, the flywheel friction causes the sprocket to turn in a circular motion.

The track motor is an integral part of all hydraulic excavators (also known as mini-excavators).

The heart of this powerful hydraulic motor is the transmission, which uses a system of linkages and gears to convert the rotary motion of the motor into straight-line action that moves the equipment forward or backward.

2.    How do I know if my excavator track motor is bad?

When you have a bad excavator track motor, you will not lose all power.

You might notice that your excavator is not moving around as easily as before, or the backhoe blades are not as sharp as they used to be.


Before you know it, you will need a new excavator track motor.

Common signs that your travel motor is bad include grinding noises, a power surge, and irregular movement. This is due to bearings that are wearing out in your machine.

A failing or bad track motor will cause the track to slip or prevent the track from turning due to a lack of motor power.

3.    What is an excavator track motor on an excavator?

An excavator track motor is a drive unit employed in an excavator responsible for picking up and moving the machine over the terrain.

The Track Motor is the power supply and control system for your machine’s track.

Excavator track motors rotate and drive the excavator tracks.

An excavator track motor is a motor that travels in a slot that has its housing.

It is usually powered by hydraulics and turns the track which moves the claws depending on which way the motor is facing.

A tracking motor is similar to a wheel and is included on all major mining equipment: excavators, loaders, bulldozers, and cranes.

4.    What’s inside an excavator track motor?

An excavator track motor consists of multiple parts. Some of the major components of an excavator track motor are listed below:

Inside the Excavator Track motor

  • The pinion gear is attached to the drive shaft.
  • A ring gear is a steel gear with a curved edge used for differential drive in vehicles.
  • The driveshaft known as the spyder shaft turns the crown wheel, which turns the spider gear. The result is that the drive pinion is rotated as well.
  • The sun gears are mounted on the shaft, and they can be spin freely.
  • The sun and planet gears are meshing together, and their teeth are meshing each other, which move on each other splines.
